""For software, I have just re-read the whole thread to remind myself of the themes here .......................................
the softwares identified in here are:-
Locus
OSMAnd
Navfree
MapDroyd
Backcountry Navigator
Androzic (Oziexplorer?)
Sourceforge
Soviet Military Maps Free
Mapquest
Google Maps
Skobbler
Viewranger
Sygic
Navigon (now owned by Garmin)
Tom Tom on Android
Ovimaps (therein lies a story)
MapsWithMe (now Maps.me)
MotionX
Navit
iOverlander (this slipped in as an IPhone OS?)
Avenza
PathAway""

That list from earlier and the increasing use and popularity of OSM led me to consider open cycle map:-
OpenCycleMap.org - the OpenStreetMap Cycle Map
This may be biased toward the UK; I don't know because I haven't looked at it in much detail, but it definitely acknowledges OSM as its' base mapping for its' own purposes.


Having just ditched Maps.me from my phone for reasons stated earlier (I think - can't quite remember if that was in this thread or somewhere else!!) I am now trying out viewranger from the list above.
First impressions are that this is a very comprehensive android navigation and mapping app.
For instance, it seems to do tracks and routes while it provides access to the following maps as routine while connected online and it can save maps for use offline:-
OSM, courtesy of Mapquest
OSM, standalone
Opencyclemap
Bing Aerial Imagery (so, a competitor to google maps imagery also on android, naturally)
Skiing map
Transport map
OR your own previously saved maps
